This application is related to and claims priority from provisional patent application No. 61/148,572, filed on Jan. 30, 2009 the contents of which are incorporated herein by reference.
The present invention relates to a device used to support at various events and in particular to a device through which one can make audible sounds such as yelling and which one can attach to his or her person when not yelling through the device.
A megaphone, speaking-trumpet, bullhorn, blowhorn or loud hailer is a portable, usually hand-held, funnel cone-shaped device whose application is to amplify a person's voice towards a targeted direction. This is accomplished by channeling the sound through a funnel, which also serves to match the acoustic impedance of the voice cords to the air. The natural human voice tends to spread evenly in all directions, whereas when it is sent through a megaphone, the sound is concentrated in a given direction and the coupling of its energy to the air optimised. The trade-off is that if a listener is to the side, it is more difficult to hear what is being said. An electronic megaphone amplifies sound to a higher decibel level. It consists of a microphone an amplifier and a loudspeaker.
Megaphones have been used for many years to project the voice of the user. Many megaphones have a generally conically shaped horn configuration, with a relatively small mouth opening which flares outwardly to the outermost broadcast end. Although various powered-type megaphones have been developed, the simplest megaphone merely relies on the horn effect to transmit the sound of the user outwardly from the user. At public sports events, the spectators show their approval/disapproval of occurrences in play actions on a more or less continuous basis. The “home” field affect is well recognized in sporting events, wherein the home crowd which is generally the largest percentage of the spectators, can affect the outcome by verbally “getting into” the game. Thus, the cheering by the home spectators can psychologically affect the attitude and play of the home team. At such spectator events, one may see spectators forming their programs into a horn shaped configuration to more fully project their voice with that of the other spectators.
When people attend various events and in particular athletic events people show their support by making noise for their teams. One thing people do is roll up pieces of paper or cup their hands together to try and project their voices toward the field of play. Some times this approach does not work very well as the people that cup their hands together didn't accomplish much and the individuals that use rolled up paper ended up with a mess that they occasionally pick up. Sometimes individuals keep the rolled up paper in their hands tightly rolled up to hold on to it and not get it dirty by laying it on the ground or bleachers. There remains a need for a device that people can used to show support for their teams that can be conveniently stored when not being used.
Various designs of megaphones are used today. One design described in U.S. Pat. No. D559,830 to Lintern is a foldable megaphone. This mega contains handles at each edge. It appears that a person uses the handles to fold the megaphone and bring the ends of the megaphone together.
U.S. Pat. No. 6,940,984 to Carpenter describes a megaphone having: a microphone assembly including means for attachment to a user adjacent to the user's mouth for hands-free operation; a body pack provided with means for attachment to the users body and incorporating an output horn; and a flexible cable connecting the microphone assembly to the body pack.
U.S. Pat. No. 4,703,829 to Hardt describes a collapsible and portable megaphone formed from a self-supporting flexible plastic sheet. The sheet is wrapped with overlapping side edges to form a horn shaped member. The overlapping edges are releasably interlocked by edge slots and interconnecting edge arms. A separate mouthpiece has a tube, which telescopes into the narrow mouth end of the horn and has an outer shaped end for coupling to the user's lips. The plastic sheet may be rolled into a compact tubular roll. The mouthpiece is placed over the roll to maintain the rolled configuration for storage and transport. The horn sheets can be readily mass-produced by stamping and the mouthpiece by molding.
United States Patent Application 20060266579 to Stern et al. describes an inflatable acoustic megaphone that can be inflated into a substantially frustoconical shape for use and deflated and folded into a relatively small space when not in use, optionally providing text and/or graphics on its surface that can be used for advertising or promotions.
Even though there are many designs for the megaphone, there still remains a need for a megaphone that is storable on the arm of the person using the megaphone.
The present invention comprises tapered ends to add comfort on the users mouth/lips during use as a sound projection device and the contour aids in comfort when the user stores the device on his/her arm. Each end of the tapered device comprises an opening. The opening at the smaller end of the tapered device fits against the user's mouth to allow sounds from the user to enter the device. The larger tapered end channels the sounds toward the participants of the event. The cone design of the present invention allows the units to be easily stacked together. In addition, the present invention has a surface area that allows the user to have a team, expression or viewpoint displayed and made known to those around him/her.
An embodiment of the present also has the capability to expand the cone shape of the device in order to allow a user to position the device around an arm or leg when the device is not in use. In this embodiment, the device can comprises a rigid material having a generally cone shape. The material has two edges that come together to form the shape. The material is rigid such that it holds its' shape. However, the material also has some flexibility that allows the user to apply pressure and move the edges apart in order for a use to position the device around his or her arm or leg. After positioning the device on the user's body, the rigidity of the device will cause the edges of the device to come back together and return it to its' original shape and thereby enclose around the user's arm or leg. When the device encloses around the arm or leg of the user, the rigidity of the device will secure it on the user.
The present invention can be used for all types of events where the user would like to be heard and express a view without being burdened with the need to hold on to the device when not in use.
Currently, fans cup the hands together or use vocal projection devices that require the user to hold on to the device to prevent loosing or soiling it when it is not in use. The present invention is a sound projection device that is to place to a user's mouth in order to project sounds from the user toward participants in an event. The present invention is a device that provides for more expressive interaction at sporting events, political events, demonstrations and other events. The present invention is a sound projection device that channels sounds from a person out into the atmosphere. This sound projection device has tapered sides which causes the device to form a generally cone-type shape. This shape allows easy storage of the device on the user's arm when the person is not using the device for sound projection. The device of the present invention can have a contour fit to conveniently fit on the arm of a person. To facilitate the contoured fit, the dimensions of the sheet of material from which the projection device is formed must be in a range that will provide a secure and comfortable fit of the device on the user's arm or leg. Devices that are too large would not securely fit around a user's arm or leg. Devices formed of material with too small dimensions will not fit around a user's arm of leg. The device also has surfaces that allow the user to display visual messages. Using two units, the user can clap the units together to create noise to support or distract participants in an event.
In another embodiment, the present invention comprises a sheet of generally rigid material having a surface with opposite ends. As in
In an alternate embodiment of the present invention, there can be a lining material positioned on the one side of the device. This lining would serve to protect the user from the elements such as cold weather. When not using the device to yell through, the device could be used to warm the user's arm.
In another alternate embodiment of the present invention, the device could have transparent compartments on both sides of the device. In this embodiment, the device could be reversible and would have the capability to display images on either side. The user would configure and close the device based on the particular image that the user wanted to display.
In another alternate embodiment of the present invention, the transparent compartments can have airtight seals, which would provide the capability to inflate the compartments.
Another alternate embodiment can have multiple transparent compartments that can be attached to the device.
In an alternate embodiment, the device of the present invention is positioned on a lamp and serving as a lamp stand. In this embodiment, the device is positioned on the lamp with the larger opening engaging the lamp. This position is opposite the position of
In another embodiment of the invention, the sheet material can be comprised of a flexible and bendable material. As with the previous embodiments, the front end of the material is smaller than the back end. The front end will form a smaller opening through the person will yell. The back end is longer than the front end. The front end should be of a length such that when present invention is positioned on a user's arm, the front end is positioned in the area of the user's wrist. Similar to other embodiments there are two side edges. These edges can also contain strips that secure these ends together to form the megaphone shape of the present invention. These strips can be magnetic strips or they can be of some other adhesive material such as the material supplied by Velcro™. The width of the strips can vary to provide the ability to adjust the device on the user's arm or leg. The material of the present convention has a rigid character. When the material is molded into a cone shape of the present invention, this material is resilient will retain or resume that shape. The edges come together, but are not permanently attached.
The method of this invention provides significant advantages over the current art. The invention has been described in connection with its preferred embodiments. However, it is not limited thereto. Changes, variations and modifications to the basic design may be made without departing from the inventive concepts in this invention. In addition, these changes, variations and modifications would be obvious to those skilled in the art having the benefit of the foregoing teachings. All such changes, variations and modifications are intended to be within the scope of this invention.
